Frequently Asked Questions

What is the most common reason for check engine light on a 2025 Land Rover Discovery Sport?

• Common causes include oxygen sensor faults, EVAP leaks (loose fuel cap), ignition misfires (plugs or coils), catalytic efficiency issues and fuel system lean/rich conditions.
• Ignoring these can reduce fuel economy, raise emissions, and lead to expensive repairs—what starts as a small sensor replacement can become a catalytic converter job.
• At Land Rover Sudbury we identify root causes quickly with OEM diagnostic tools, helping you avoid long-term costs while often costing less than independent shops.
• Warranty-covered repairs must be done at a certified dealership to remain protected—our factory-trained technicians ensure proper repairs and documentation.

How much does a check engine light diagnostic cost for a 2025 Land Rover Discovery Sport?

• Diagnostics typically range depending on scope; many scans are in the $99–$199 range, with full diagnostics and road tests varying by time required.
• Land Rover Sudbury frequently offers better value than independent shops when you factor in accurate OEM scans, verified parts, and correct programming.
• Immediate savings come from precise diagnostics that prevent unnecessary parts replacement; long-term savings come from repairs done right the first time.

What does it mean when the check engine light comes on in a 2025 Land Rover Discovery Sport?

• A steady light signals a detected fault in emissions, engine management, or sensor systems; it flags a problem that needs scanning but may not be immediately catastrophic.
• A flashing light indicates an active misfire or condition that can damage the catalytic converter—stop driving and have it inspected immediately.
• We recommend scheduling a prompt diagnostic at Land Rover Sudbury; our OEM tools read stored codes and live data so we can recommend the right repairs.
• Using our dealership often costs less over time than independent shops because accurate diagnostics and factory procedures reduce repeat visits and premature part replacements.

What is the first thing to check when the check engine light comes on?

• Start with the basics: check that the fuel cap is tight (a loose cap commonly triggers EVAP codes) and verify recent fuel quality and oil level.
• Listen for rough running, note drivability changes (hesitation, stalling), and avoid hard acceleration until diagnosed.
• Bring your vehicle to Land Rover Sudbury for an OEM scan—our technicians connect manufacturer-level tools that pinpoint the issue and prevent unnecessary part swaps.
• If a warranty repair is needed, have it completed at our certified dealership to preserve coverage and ensure genuine parts and calibrated programming.

How long does a check engine light service take?

• Initial scan and code review typically take 30–60 minutes; additional time depends on troubleshooting, road testing, or live-data capture needs.
• Some repairs are completed the same day (sensor or fuel cap fixes); more complex jobs requiring parts or calibration may require one or more business days.
• At Land Rover Sudbury we prioritize efficient scheduling and use OEM procedures to reduce repeat visits—often saving you time and money compared with independent shops.
• If the repair is under warranty, performing it at a certified dealership ensures proper authorization and quicker resolution without risking coverage loss.
